Fire indicates a chemical change.
Fire indicates a chemical change.

The soot and sulfur from the fire is a chemical property. A chemical property is a change you see after a chemical change, it's a change that alters the original structure. It might change the phase of matter or change it completely.
(The burning of the wood is an example of a chemical change.)

The fireworks are an example of a chemical change because inside the fireworks are magnesium and copper and when you let them off they explode. The magnesium and copper change chemically when they burst. A chemical change is when a substance changes into a new substance.
